[[File:Notice.jpg|left|Notice.jpg]] Do not confuse the BAUD statement with the [[$BAUD]] compiler directive.

 

And do not confuse [[$CRYSTAL]] and [[CRYSTAL]]

 

$BAUD overrides the compiler setting for the baud rate and BAUD will change the current baud rate.

So $BAUD is a global project setting in your source code while BAUD will change the baud rate during run time.

You could use BAUD to change the baud rate during run time after the user changes a setting.

 

BAUD = ... will work on the hardware UART.

 

BAUD #x, yyyy will work on the software UART.

'Now change the baud rate in a program

+When you use a software UART and change the baud rate at run time using BAUD, you must set the baud rate after the OPEN statements as well.
